Dear Release Team,
I would like to propose an upload of batik in the next point release.
[ Reason ]
CVE-2022-44729 and CVE-2022-44730 have been filed against batik. They are fixed
in sid (and soon trixie). I discussed with Security team, they said a DSA is
not needed but suggested to fix the CVE in bookworm in a point release.
The two CVE are corrected by backporting upstream changes.
[ Impact ]
The two CVE would remain:
``A malicious SVG can probe user profile / data and send it directly as
parameter to a URL.''
and
``A malicious SVG could trigger loading external resources by default, causing
resource consumption or in some cases even information disclosure.''
[ Tests ]
The rdepss using the classes touched by upstream corrections were rebuilt in a
bookworm chroot. No additional tests were made.
[ Risks ]
Code is quite trivial and it is a direct backport of changes made in version
1.17, currently in sid. Risks due to the changes in the code are quite limited
in my opinion, but batik has many rdeps so you might consider the security
risks are not important enough to deserve an update in a point release.
[ Checklist ]
[X] *all* changes are documented in the d/changelog
[X] I reviewed all changes and I approve them
[X] attach debdiff against the package in stable
[X] the issue is verified as fixed in unstable
[ Changes ]
Changes are in 7 files and consist in:
- Blocking loading external resource by default
http://svn.apache.org/viewvc?view=revision=1905049
- Switching to empty whitelist of packages for the class RhinoClassShutter
https://svn.apache.org/viewvc?view=revision=1905011
Thanks for your attention,

Pierre
